Let's divide 368090 by 86
The aim is to understand the frequency of 86 in 368090.

Going ahead to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 86

On to step 2:
86 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 86

On to step 3:
If we divide 368 by 86, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 24 after subtracting 344 from 368.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 86

Step 4:
The number 86 fits into 240 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 172 from 240 leaves us with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 86

Step 5:
86 goes into 689 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
If we take 688 away from 689, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 86

Going ahead to step 6:
If we divide 10 by 86, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4280.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 86, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 4280.1
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
86 goes into 140 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 4280.11
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 4280.11 with a remainder of 0.054.
